Equatorial ionospheric electric fields during magnetospheric disturbances: local time/longitude dependences from recent EITS campaigns
TLDR
In this paper, the response of the equatorial isonospheric heights and ionization anomaly to disturbance electric fields, identified as a direct penetration electric field associated with IMF B, changes and development of the ring current (especially the asymmetric component), and that produced by a disturbance zonal neutral wind are analyzed.About:

Effects of the vertical plasma drift velocity on the generation and evolution of equatorial spread F
TL;DR: In this paper, the authors used radar observations from the Jicamarca Observatory from 1968 to 1992 to study the effects of the F region vertical plasma drift velocity on the generation and evolution of equatorial spread F.

Penetration of high latitude electric fields effects tolow latitude during Sundial 1984
TL;DR: In this article, electric field penetration events were identified using F-region vertical-drift measurements obtained in the October 6-13, 1984 period by Jicamarcan incoherent-backscatter radar and corresponding h-prime F measurements from ionosondes at Fortaleza, Cachoeira Paulista, and Dakar.

Quiet time equatorial F region vertical plasma drift model derived from ROCSAT‐1 observations
TL;DR: In this article, the authors used five years of measurements on board the ROCSAT-1 satellite to develop a detailed quiet time global empirical model for equatorial F region vertical plasma drifts, which describes the local time, seasonal and longitudinal dependence of the vertical drifts for an altitude of 600 km under moderate and high solar flux conditions.

The ionospheric disturbance dynamo

TL;DR: In this article, a numerical simulation study of the thermospheric winds produced by auroral heating during magnetic storms, and of their global dynamo effects, establishes the main features of the ionospheric disturbance dynamo.

TL;DR: In this article, the authors combined ground-based incoherent scatter radar and Fabry-Perot optical interferometers to generate a revision (HWM90) of the HWM87 empirical model and extend its applicability to 100 km.
Journal ArticleDOI
An explanation for anomalous equatorial ionospheric electric fields associated with a northward turning of the interplanetary magnetic field
TL;DR: In this paper, the authors suggest that anomalous reversals of the zonal equatorial electric field component are associated with a sudden change in the convection electric field in the magnetosphere and present measurements to support this explanation.

Polarization fields produced by winds in the equatorial F-region
TL;DR: In this article, the E-layer conductivity may be too small to close this circuit, so that polarization fields build up in the F-layer, causing the plasma to drift with the wind.
Journal ArticleDOI
The prereversal enhancement of the zonal electric field in the equatorial ionosphere
TL;DR: In this paper, it was shown that after sunset, the ionospheric conductivity decreases far more rapidly in the E region than in the F region, and that the enhancement of the eastward field for an eastward F region wind turns out to be a simple direct consequence of the fact that the E and F conductivities are different.
